I'm trying to make a mid-to-small size hangar, 30 m lenght, 8 m height, and 60 m width. I tried with modular pieces but textures doesn't match, i tried the hole building in separed walls with similar UVs (the hangar is done with 3ds max), i tried to do the UVs of all the buidling at once, but once i put it some textures in substance painter, the texture looks really poor Quality.
So, what would be the best way to paint that kind of hangar in Substance Painter? (the image bellow is just a test to show you the size of the hangar)
Where a building is to be viewed both at a distance and close up, I try and ensure sufficient texels in the image for that close view. To do that I split the surface and use UV tiles (UDIMs). That does not mean every surface has to be textured at that close up resolution. Some parts may only be viewed at a distance (e.g. the roof). The resolution of the texture used in each tile does not have to be the same.
